When Bitspark has completed the integration of ZEPH and the switch to Bitshares pegged cryptos is done, then the new bitassets will be added- timelines are mentioned in our updates here: https://steemit.com/blockchain/@bitspark/bitspark-zephyr-update-7 The idea is Bitspark will be creating private smartcoins ('private feeds' meaning price feed fed not by the committee) at the start for our relevant currencies and later this year for all global currencies. Some currencies are already pegged to USD and EUR however and in those cases we will piggyback off the existing liquidity in BitUSD/BitEUR and not introduce smartcoins for them.
